I too try to do our own maintenance...It sometimes feels like a 'contest' to see who wears out who... FIRST!
That said, RVing is worth every trial and tribulation to be able to drive this big picture window throughout this great nation of ours. In the little over two years we owned 'Squeaky' we've visited 42 states, 3 Canadian Provinces, 36 National Parks and other national treasures that we were aware of but had no idea of their scope. In that context, cost pales in comparison. As someone once said "I do not regret the things I've done, but those I did not do".
